I want to buy scraper like seo frog with : 1. threads up to 500 . 1000 will much prefered. 2. to scrap only one site.. every link. like seo frog , but it has only 200threads max and i can scrape with more than 1000. Also if it can saving the caches on hdd its prefered becouse with 64gb ram its not possible to scrape big big sites.. seo frog save caches of the crawled pages on the ram .. too bad for a disent scraper.
